Waterproofing solutions by application
Start with the part of your project that needs waterproofing. Explore five application areas, then review the relevant products and technical data.
Basement & Foundation Waterproofing
Waterproofing for basement rafts, below-ground walls and foundation structures. Select the membrane around the concrete-pour sequence and access to the external face.
Key details to plan
Coordinate the raft-to-wall connection, pile heads, construction joints and pipe penetrations. Confirm adhesive-lap or welded-lap details, inspect the membrane and repair damage before concreting.
Products to review
Provide groundwater conditions, design water pressure, drawings and the proposed construction sequence for selection.
Exposed Roof Waterproofing
For weather-exposed roofs, terraces and roof refurbishment. Compare liquid coating and sheet membrane options according to the substrate, roof geometry and maintenance access.
Key details to plan
Plan drainage, falls, outlets, upstands and penetrations. Confirm UV exposure suitability, substrate compatibility and the selected system’s attachment or reinforcement details.
Products to review
Use the UV-resistant BIOGO-WS grade for exposed work. Confirm ponding conditions, traffic and application temperature limits.
Protected Roof & Podium Waterproofing
Continuous waterproofing beneath the specified protection or finish on non-exposed roofs and suitable podium assemblies.
Key details to plan
Prepare the substrate, reinforce corners and joints, and maintain the specified film or membrane thickness. Inspect the completed waterproofing before installing compatible isolation and protection layers.
Products to review
Choose the product grade and protection build-up for the load, movement and project design. These PU options require suitable protection in non-exposed assemblies.
Bathrooms, Kitchens & Balconies
Waterproofing beneath suitable finishes in bathrooms, kitchens and balconies, with particular attention to floor drains and wall-to-floor junctions.
Key details to plan
Repair the base, form falls and seal penetrations. Reinforce critical details, apply the selected system to its specified thickness and test after full curing before covering.
Products to review
Confirm compatibility with the finish and tile adhesive. BIOGO-J20 is for the stated non-permanent-immersion uses; exposed balconies need an exposure-suitable system.
Waterproofing Repair & Maintenance
Options for suitable leaking façades, damp concrete or masonry and local waterproofing repairs. Identify the water source and substrate condition before choosing a treatment.
Key details to plan
Check whether leakage comes from cracks, joints, failed sealants or the surface itself. Prepare a trial area, repair the underlying defect and select a compatible clear, vapour-permeable, mortar or crystalline treatment.
Products to review
BIOGO-C is for suitable cementitious substrates. Match repairs to the leakage mechanism; surface coating alone may not resolve moving joints or structural cracks.
