Learning Catalogue
How waterproofing systems are chosen and applied.
Sika and Master Builders Solutions products, explained by what they are, where they go, and what an applicator must check before starting.
This is a learning catalogue, not a stock list. A product appearing here does not mean it is stocked or approved in Rwanda. Names, formulations and approvals vary by country and product generation.
Each entry shows how confident we are in the name. Always confirm the exact product against the current manufacturer data sheet, and ask us before you specify.
- Current family
- A current product family. Choose the exact grade from the manufacturer data sheet.
- Verify locally
- Listed by the manufacturer or a regional catalogue. Confirm formulation and availability for your market before specifying.
- Legacy / market-dependent
- A historical, regional or rebranded name. Do not treat it as a current product until it is verified.

Waterproofing terms, in plain language
- Substrate
- Surface receiving a coating or membrane, such as concrete, screed, masonry or metal.
- Surface preparation
- Removal of dust, laitance, oil, weak material and contamination to obtain a sound surface.
- Primer
- Preparatory material used where specified to improve adhesion or regulate absorption.
- SSD (saturated surface dry)
- Mineral substrate is saturated internally but has no standing surface water; only use this condition when the product TDS requires it.
- Hydrostatic pressure
- Pressure exerted by water on a structure or waterproofing system.
- Positive-side waterproofing
- Applied on the side from which water approaches the structure.
- Negative-side waterproofing
- Applied on the opposite side, where water pressure may challenge adhesion.
- Wet-film thickness (WFT)
- Coating thickness immediately after application.
- Dry-film thickness (DFT)
- Coating thickness after drying/curing.
- Crack bridging
- Ability of a membrane to span a crack within a stated movement limit.
- Pot life
- Usable time after components are mixed.
- Recoat interval
- Allowed time before applying the next layer.
- Curing
- Process that lets a cementitious or resin material develop its properties.
- Lap/overlap
- Overlapping area between adjacent sheet membranes.
- Termination
- Detail where a membrane ends and is sealed to adjoining construction.
- Waterstop
- Profile or strip used to block water through a concrete joint.
- Coverage rate
- Quantity of product required per unit area at a specified thickness.
- Capillary action
- Movement of moisture through small pores in porous materials.
- Rising damp
- Moisture moving upward through masonry from the ground; confirm the cause before choosing a treatment.

- Water remaining on a surface instead of draining.
- Hydrophilic waterstop
- Material that swells when exposed to water.
- Injection packer
- Fitting installed in a hole/crack to inject repair resin under controlled pressure.
A quality-control sequence for any waterproofing job
Adapt it to the system you are installing. The product data sheet always decides the details.
- 1Inspect and diagnose the source of water; distinguish leaks, rising damp, condensation, drainage failure and cracks.
- 2Check substrate strength, moisture and contamination; repair voids and weak concrete.
- 3Select a complete compatible system, including joints, corners, penetrations, drainage and protection.
- 4Apply primer, membrane/coating and reinforcement only as specified in the product/system TDS.
- 5Record product batch, mixing ratio, coverage, layer thickness, weather and curing conditions.
- 6Inspect details and seams before covering the work; conduct a suitable water test only where the system and project specification permit.
- 7Protect the system from puncture, UV, traffic, backfill or chemicals as required.
