TopProof
Waterproof concrete
TopProof waterproof concrete offers a simple, cost effective alternative to traditional waterproof construction methods. Concrete is naturally porous. This can be a problem for sites exposed to harsh weather conditions, chemical attacks, high humidity and for surfaces that are in constant contact with water. TopProof watertight concrete uses specialist admixtures to produce concrete with very low porosity.
When used in conjunction with approved secondary and tertiary waterproofing systems, TopProof waterproof concrete offers a fully watertight system. Depending on the specification, it saves time by eliminating the need for additional membranes or finishes. It also enhances resistance to chloride diffusion, reducing the risk of reinforcement corrosion and improving long term durability.
TopProof is an integral watertight concrete solution for various applications as defined in BS8102:2022.

TopProof water tight concrete is suitable for the construction of river or flood defences, delivering excellent durability and water resisting performance.
Why use TopProof?
Additional info
Concrete is naturally porous due to its capillaries forming migratory paths for water to pass through. This porosity can be reduced by adding special active components which block these capillaries, effectively sealing the concrete permanently against the penetration of water and harmful chemicals. TopProof waterproof concrete is designed to meet the requirements of waterproofing as defined in BS8102 (all grades).
The use of specifically tailored admixtures provides TopProof watertight concrete with structurally integral waterproofing. This enables concrete to be poured and compacted with ease in comparison to barrier type products or membranes which function only at the surface of the concrete.
TopProof waterproof concrete can provide a fully integral watertight system, as defined in BS8102:2009, when used in conjunction with secondary waterproofing systems.
TopProof is an ideal cost effective watertight concrete solution for all types of structures that will require retaining the water either in or out.
TopProof waterproof concrete is available with three types of waterproofing admixtures, Hydrophobic Powder, Hydrophobic Liquid and Crystaline Powder, each selected based on client requirements.
Hydrophobic Powder is a powder admixture using hydrophobic and pore blocking technology to create polymer barriers inside pores during the hydration process.
Hydrophobic Liquid is a liquid admixture using hydrophobic and pore blocking technology to create barriers inside pores during the hydration process.
Crystaline Powder is a powder admixture that uses self healing crystalline technology to form a non-soluble crystalline structure, blocking capillaries.
