Elastomeric and Cementitious crystallisation are active and flexible coating systems applied as an internal slurry. Utilising and reacting with free lime in concrete, they block cracks and capillaries.

Area of use:

• New build basements.

• Any new Underground Structures.

• Below ground structures.

• Car parks.

• Retaining walls.

• Swimming pools.

• Lift pits.

• Tunnels.

• A concrete structure that is designed to experience and resist the penetration of water under pressure

What you should consider:

• Type B should not be relied on for Podium Decks without secondary protection

• Type B waterproofing should be installed by suitably experienced and trained operatives who are fully aware of the requirements for placing concrete used in Type B systems

• A risk assessment should be carried out which identifies any possible long-term water pressures, the effects of surface water percolation, use of external drainage and the effects of party wall impaction on neighbours
• The design of the waterproofing system should consider the likely effects of these ground conditions, including water, and assume exposure of the basement to full height of water within the design life of the building

• Type B systems can NOT provide methane or radon resistance as a standalone system unless incorporating a membrane

• We recommend using ready-mixed concrete suppliers operating under the quality scheme for ready mixed concrete (QSRMC) or BSI Kite-mark scheme only
