Soudal HB Construct – Adhesion Without Clamping

The extra strong PU Adhesive that doesn’t require clamping.

HB Construct from Soudal is a unique waterproof (Grade D4), hybrid polymer based adhesive with extra strong adhesion.

It can be used to bond many substrates in the joinery and construction industry, including wood, wood based materials, glass, aluminium, steel, many types of plastics, tiles, concrete, brick etc. However, at least one of the surfaces should be porous.

HB Construct works differently to PU Adhesives as there is no ‘foaming’ action whilst curing meaning clamping is NOT required, however the product still withholds an amazing end strength of up to 110kg/cm².
