How we view Waterproofing

Being the pioneer in liquid applied polyurethane waterproofing membranes, ALCHIMICA has been reshaping the global waterproofing market for over 39 years.

Starting with the invention of HYPERDESMO® in 1983, a breakthrough for the waterproofing industry, we have shifted the focus worldwide from multi-layer systems, traditionally thought to guarantee water-tightness, to new systems based on advanced technology liquid membranes.

Liquid-applied systems, of which polyurethane waterproofing membranes are the prime example, offer decisive advantages particularly where seamless systems are desired; either structurally or aesthetically, and for geometrically complicated connections with ventilation outlets or upturns.

Critical to success is the correct material selection from the various alternatives in the market.

Throughout the years we have been continuing our tradition in innovation providing solutions with our extensive range of polyurethane liquid membranes which are the most versatile and long term performing of the liquid applied membrane waterproofing category of products.

Our vast product range contains one and two component polyurethane liquid membranesbitumen extended polyurethanes, water- based liquid polyurethane membranes and advanced technology polyurethane dispersion (PUD) products that answer to any type of waterproofing problems.

Our products have been applied successfully to numerous applications, such as: roof waterproofing, wet rooms, water/ sewage treatment plants, stadium stands, bridge decks, car parks, swimming pools, foundation walls and retaining walls.
