Supplied product documents
These summaries are attributed to the technical sheets supplied with the website. Confirm the latest revision, availability and project-specific suitability before ordering. They do not establish an Aamtron certification, installer accreditation or warranty.

Specify the exact product
A cementitious coating is a category description, not a complete specification. Provide the substrate, exposure, expected movement, finish and use. Ask Aamtron to confirm whether the requested item is within the available SR or SF range and suitable for the proposed work. Availability, packaging and individual product performance are subject to confirmation.
Check compatibility and application instructions
Request the current technical and safety documents for the proposed product. Confirm preparation, primer, application conditions, coverage or thickness, curing and protection. Do not infer immersion suitability, drinking-water approval or a certification from a general material name.
Review the whole assembly
Include interfaces with drains, joints, repairs and the final finish in the proposed system. A product supplied for one purpose cannot be assumed suitable for another. For a comparison, read PU and bituminous waterproofing and cementitious and liquid systems.
Request a material or installation quotation
State whether the enquiry is for supply or supply with installation, and include drawings or a specification if available. Contact Aamtron; see the material enquiry overview.
Questions before you start
Discuss your waterproofing requirements
Cementitious waterproofing: what to check before specifying it
Cementitious waterproofing uses a cement-based coating system on a suitable mineral substrate. The term describes a family of materials rather than a universal specification. Products differ in flexibility, mixing requirements, exposure limits and approved uses. Aamtron supplies and installs SR and SF waterproofing systems; confirm the exact product and application before ordering.
For a concrete surface, start by identifying the source and direction of water exposure. A coating intended for one condition should not be assumed suitable for another. Below-ground groundwater, occasional bathroom wetting and a permanently filled tank impose different requirements. Read the current product documentation alongside the project specification.
Rigid and flexible systems
Some cementitious systems are relatively rigid; others include a polymer component or are formulated to accommodate defined movement. Neither label establishes that a product can bridge every crack or movement joint. Record the condition of the concrete and the location of joints. A moving joint needs a designed detail rather than simply another coat over the joint.
Use our cementitious versus liquid waterproofing comparison to understand the selection questions. The relevant difference is how the complete system meets the project conditions, including the finish above it and protection during later work.
Bathroom, basement, pool or tank?
For bathrooms and wet areas, confirm the substrate, falls, drains, wall-to-floor junctions and compatibility with the tile adhesive and finish. A waterproof coating should not be expected to correct drainage falls. The sequence must allow for curing, inspection and protection before the next trade begins.
For basements, establish whether the water-facing side is accessible and whether there is active ingress. The condition of construction joints, tie holes and penetrations matters as much as the area of wall or slab. Do not assume that a coating approved for damp concrete is suitable for the actual water pressure.
For swimming pools, check the shell, fittings, intended finish and exposure conditions. Tile grout alone should not be treated as the waterproofing layer. Confirm the full build-up and the sequence for testing before finishing or filling.
For water tanks, identify whether the water is potable or used for another purpose. Obtain documentation for the specific material’s intended water-contact use. A general waterproofing description is not proof of potable-water suitability.
Preparation, mixing and application
The technical data sheet should define preparation, surface condition, mixing and application. Remove material that prevents bonding and address substrate defects through a suitable repair specification. Do not add extra water or alter component proportions to make application easier. That changes the product from the manufacturer’s stated system.
Confirm the required number of coats and the specified thickness or consumption for the selected product. Coverage depends on the actual substrate and application requirements; an advertised pack size does not by itself establish the area that will be waterproofed. Record the system requirements in the quotation and installation method.
Qatar site conditions require planning around the substrate temperature, exposure and working period. Follow the product’s stated limits and protection requirements. Avoid relying on a generic curing time taken from a different brand or a different coating chemistry.
Details, protection and inspection
Prepare a detail schedule for corners, pipe entries, drains, upstands, terminations and joints. Confirm whether reinforcement or accessory components are part of the chosen system. Compatible detailing materials should be identified by name, rather than described only as “sealant” or “mesh”.
Agree how the completed coating will be protected against later damage. Tiling, screeding, backfilling or other finishing work can compromise a sound waterproof layer. Inspection photographs and hold points help the client and contractor establish what was checked before an area became concealed.
Testing should suit the structure and the selected system, with curing completed and any required approvals in place. Where a water test is proposed, confirm its duration, loading, isolation and acceptance criteria through the project method. See the waterproofing inspection checklist for questions to include in the work scope.
Request the current product document
The available documents on this page help identify SR and SF product names and manufacturer instructions. Ask for the current revision and confirm availability before procurement. If your specification names a performance requirement, provide that requirement rather than assuming that any cementitious coating is interchangeable.
Send the substrate, application, approximate area and intended finish to Aamtron. These details provide a more useful starting point for material selection and a written scope than a request for a price per pack alone.
