A useful waterproofing quotation starts with information about the property, the water problem and the responsibilities expected from the contractor. A square-metre figure alone cannot show whether repairs, removal, difficult access or another trade are involved. This checklist is for villa owners, facility managers and main contractors preparing work in Qatar. It helps organise an enquiry for Aamtron’s SR and SF waterproofing supply and installation services without inventing prices, programme dates or warranty promises. Use it alongside the relevant product instructions and project specification; it is not a substitute for a competent site assessment.
Identify the property and the requested area
Record the location and a practical access reference, then describe the part of the building requiring work. Specify whether it is a roof, bathroom, basement, pool or concrete water tank. Explain whether the property is occupied, under construction or being refurbished. Include approximate dimensions and drawings where available, but label estimates clearly. A contractor should know whether the enquiry concerns material supply, installation or a combined scope. For shared buildings, identify the person who can authorise access and alterations. The initial description should help organise the assessment without implying that the product, preparation or price has already been decided.
Describe symptoms and previous work
Record when the problem appears, the affected rooms and any relationship to rainfall, water use or equipment operation. Photograph visible dampness and the area above or around it where access is safe. Provide the history of previous coatings, grout repairs, pipe works or roof changes, with dates if known. Explain what was repaired and whether the symptoms changed afterwards. An old quotation or product reference can be useful even when the work did not resolve the issue. Avoid treating every wet patch as membrane failure. The investigation may need to distinguish plumbing, drainage, condensation, joints and structural conditions before a waterproofing scope is established.
Photograph the wider construction and the details
Take a wide view so the assessor can understand the arrangement, followed by clear photographs of cracks, outlets, corners, joints and penetrations. Include changes in level and interfaces with adjacent finishes. Do not put yourself at risk to obtain an image from a roof edge, restricted pit or tank. Where access is unavailable, state that limitation and arrange an appropriate inspection. Images should support an enquiry, not be treated as proof that remote assessment is sufficient. Keep originals and dates rather than heavily edited pictures. If a detail becomes covered during construction, photographs taken at the agreed inspection stage may help document what was installed.
Establish who checks plumbing and structural issues
A waterproofing contractor cannot automatically take responsibility for every connected building system. If pipe leakage or structural damage is suspected, identify the competent professional who will assess it. Record relevant findings before the membrane is applied. Repairs may need to be designed or carried out separately, with a handover between trades. Do not ask a coating to restore a structural defect or assume new grout confirms the condition of hidden pipework. The quotation should state the boundaries between investigation, repairs, waterproofing and finishing. Aamtron’s confirmed scope is waterproofing supply and installation; additional specialist capabilities need to be agreed for the particular project.
Check the substrate and retained layers
Ask which surface the new system will bond to and how its condition will be verified. Existing coatings, tiles, screed, dust, loose concrete and contamination can affect preparation. An overlay may be appropriate only where the retained build-up is sound and compatible. Removal can change floor levels, waste quantities and access requirements, so clarify it before comparing prices. The exact product’s technical documents govern moisture limits and other substrate requirements. A phrase such as clean and prepare should be supported by a meaningful method and scope. Record any assumptions that cannot be confirmed until opening or inspection reveals the construction beneath the finish.
Request the complete proposed waterproofing assembly
Identify the products, primer where needed, reinforcement, membrane, detail accessories and protective or finishing layers. Confirm the intended application and exposure for the particular product, rather than relying on a broad brand description. If the structure stores drinking water, ask for documentation applicable to the exact product and system; no general waterproofing label establishes that suitability. Tiles, adhesives, screed and coatings should be coordinated where they form part of the build-up. Ask how joints, drains and pipe entries connect to the main layer. The written system proposal is the reference against which materials and application can later be inspected.
Define preparation and repair responsibilities
Separate removal, substrate repairs, crack or joint treatment, drainage adjustments and waterproofing application. State who provides access equipment, isolates services, protects furnishings and removes waste. When a different contractor performs tiling or reinstatement, agree the inspection and handover between them. A quotation can otherwise leave essential tasks outside every trade’s scope. For new construction, specify how later work will avoid damaging the membrane. For occupied properties, identify the working boundaries and the areas that must remain available. The purpose is to make the job comparable and deliverable, rather than to add every imaginable task to a coating price.
Agree inspections before concealment
Create inspection points for the prepared substrate, detail treatment, completed membrane and protective layers as appropriate to the system. The responsible people should know when they need to attend and which records are required. Photographs, product references and coverage or thickness observations may be useful, but the method must match the agreed specification. Do not rely solely on the appearance of the final tiles or paint to prove the hidden waterproofing is complete. Aamtron’s work should be described by its actual inspected scope, without unsupported certification claims. Where a consultant or main contractor controls acceptance, confirm their requirements before work begins.
Set a suitable testing and return-to-use plan
Confirm the required curing before testing, covering or putting the area back into service. A bathroom, roof, tank and basement may need different inspection and testing approaches. Identify who provides water, monitors observations and approves the result. Avoid a universal flood-test duration without checking the product and structure. For a tank or pool, coordinate drainage, equipment and return-to-use responsibilities with the relevant specialist. The programme should account for repairs and finishes as well as application time. Record what happens if a test reveals a defect. An accepted test is evidence of the conditions checked, not a guarantee against all future damage or unrelated leakage.
Compare quotations line by line
For each proposal, list the covered area, preparation, repair assumptions, exact system, protection, access, testing and reinstatement. Ask whether taxes or other charges are included rather than guessing from a headline figure. Compare like-for-like responsibilities before judging a rate. If one contractor includes removal and another assumes an overlay, request clarification of the underlying condition and compatibility. Aamtron does not publish unverified standard rates for every project. The waterproofing cost guide explains why area is only one input. Written exclusions are useful because they identify what another contractor or the owner still needs to arrange.
Confirm warranty and handover documents
Ask for the project’s actual warranty wording, including the covered work, period, conditions, exclusions and reporting process. Do not infer a term from anonymous testimonials or an advertising badge. Retain the accepted scope, product documents, inspection photographs and test results with the property records. Identify the maintenance requirements and restrictions on later drilling, equipment installation or alterations. A clear handover makes future investigation easier if new symptoms appear. This website publishes no unconfirmed warranty duration, years-in-business figure or completed-project statistic. The useful assurance is a documented agreement that describes who supplied and installed which system, where it was applied and how it was checked.
Prepare and send the enquiry
Bring together the location, dimensions, photographs, symptom history, drawings, intended finish, access limits and requested responsibilities. Choose the relevant roof, bathroom, basement, pool or tank page for further scope guidance. Review the materials catalogue if the enquiry concerns supply. Use the contact page to prepare your WhatsApp message, then review and send it in WhatsApp. Preparing a message or clicking a button alone does not establish that the business has received an enquiry.
Questions before you start
Can photographs replace every site inspection?
No. Images help prepare an enquiry, but concealed conditions, access and technical suitability may still require inspection.
What is needed before a price can be compared?
The coverage, preparation, repairs, system, protection, testing, access and exclusions should be comparable.
Does preparing the WhatsApp form send my enquiry?
No. Review and send the prepared message in WhatsApp to deliver it.
