Permatite - Integral Waterproof Concrete
Permatite is a watertight concrete system suitable for basements, swimming pools, lift pits, green rooftops and many other structures that require effective waterproofing.
Waterproof concrete
- Keeps water out, or in as required
- Reduced risk of reinforcement corrosion
- Enhanced long term performance
- Increased Durability
CEMEX Permatite, available exclusively from CEMEX UK, is a concrete designed to meet the requirements of waterproofing as defined in BS8102 (all grades). The use of specifically designed admixtures provides Readymix Permatite with structurally integral waterproofing, enabling concrete to be poured and compacted with ease

In practice this is achieved by changing the composition of standard concrete to maximise water resistance and/or by inserting a vapour barrier, such as an impermeable membrane, during construction.
CEMEX and Fosroc, two of the leading exponents of moisture barrier construction technology, have combined their expertise and experience to provide the best solution in every application. This includes Type A (use of a waterproofing membrane) Type B (structural use of concrete) and Type C (drained cavity) construction projects.

- Keeps water out, or in, as required
- Reduced risk of reinforcement corrosion
- Enhanced long term performance including increased durability
The admixtures in CEMEX Permatite provide:
- Reduced water and water vapour permeability
- Reduced porosity
- Reduced drying shrinkage
- Enhanced Chloride diffusion resistance

CEMEX Permatite is a type B integral waterproofing system manufactured by CEMEX utilising Fosroc’s state of the art waterproofing technology. The product is manufactured in closely controlled, quality assured ready mixed plants throughout the UK and is readily available from all of CEMEX’s readymix concrete plants. The product is delivered in traditional readymix concrete delivery vehicles and requires no special handling when it arrives on sites. It is generally supplied at high consistence levels to facilitate placing and is available in a range of strength grades and cement types to suit most applications.
Designing and constructing a concrete structure to be watertight requires good crack width control, waterstops in joints and a waterproof concrete. CEMEX Permatite provides the waterproof concrete by careful selection of raw materials and optimisation of mix designs to facilitate concrete placement. Fosroc will supply all the ancillary products required to complete the construction of a watertight concrete structure.
To fully ensure a waterproof structure it’s essential to follow good concrete practice and it’s important to ensure that the concrete is fully compacted and cured. The formation of watertight joints is critical to success and Fosroc’s design team is available to give advice on the most appropriate technology for particular structures.
CEMEX will provide you access to our highly experienced technical team who will be able to create bespoke mixes for all your readymix concrete needs. Our technical team has a vast experience of producing unique mixes for individual jobs, and can facilitate issues such as corrosive ground conditions, extreme weather conditions and high strength requirements. CEMEX will work to your specification, or if requested provide suggestions to ensure that we meet the specific needs of your project.
