Here are the main products.

Voltex  -Self-bonding, composite needle-punched sodium bentonite / geotextile waterproofing membrane.

VOLTEX is a highly effective waterproofing composite of high strength geotextile and 4.88 kg of sodium bentonite per square metre. The high swelling, low permeable sodium bentonite is encapsulated between a non-woven and woven geotextile. A patented needle-punch process interlocks the geotextiles, forming an extremely strong composite that maintains the uniform coverage of bentonite, as well as protecting it from inclement weather and construction related damage. Once backfilled, VOLTEX hydrates and forms a monolithic waterproofing membrane. VOLTEX contains zero VOC, can be installed in almost any weather conditions to green concrete, and most importantly, has proven effective on both new and remedial waterproofing projects worldwide. Datasheet


Waterstop RX101- Self-injecting hydrophilic waterstop for concrete construction joints.

WATERSTOP RX101 is a sodium bentonite based waterstop designed to stop water infiltration through cast-in-place concrete construction joints by expanding upon contact with water to form a positive seal against the concrete. The key to WATERSTOP RX101 effectiveness is its 75% sodium bentonite content, which provides superior expansion to seal and fill voids and cracks in the concrete. WATERSTOP RX101 is an active bentonite based waterstop that is designed to replace passive PVC/Rubber waterbars, thereby eliminating the requirement of special pieces, split-forming and seam welding. Datasheet


Bentoseal – Trowel-grade sodium bentonite sealant used as a detailing accessory product for VOLCLAY Waterproofing Systems

BENTOSEAL is used primarily as a termination / continuity detailing compound for lapping VOLTEX with brush-applied coatings (e.g. VOLSEAL waterproofing range), and laps with continuity waterproofing membranes, particularly at / just below ground level (laps with VOLSHEET DPC, etc. Datasheet



CETBIT 300 is a self-adhering waterproofing membrane consisting of 1.4 mm of rubberized bitumen integrally bonded to a 0.1 mm cross-laminated HDPE protective film. These two components combine to offer an extremely effective waterproofing barrier with a factory controlled thickness to ensure uniform application. The cross-laminated HDPE film provides dimensional stability to the membrane plus ensures uniform reaction to elongation stresses in both longitudinal and transverse directions. CETBIT 300 is supplied in 1.0 m wide by 20.0 m long rolls. The rubberized bitumen is covered with a siliconized release paper which is removed immediately prior to installation. The membrane is self-adhering and cold-applied. No special equipment or adhesives are necessary to form laps. CETBIT 300 requires accessory products for surface conditioning and detailing, such as penetrations, corners, and terminations. Datasheet
