Toplite Foundation
Foundation is produced specifically for use below DPC in solid walls. It replaces the inner and outer leaf, wall ties and concrete cavity fill associated with traditional construction methods. This means that construction time may be halved compared to cavity walling and that the wall becomes stable soon after laying, eliminating the risk of collapsed cavities.
