For bathrooms and showers, Sakhat recommends IDROLASTIC A+B.

IDROLASTIC A+B is a two-component elastic cementitious waterproofing mortar suitable for horizontal and vertical surfaces, including bathrooms and showers.

Sakhat recommendation:
Bathroom / Shower → IDROLASTIC A+B

Sakhat recommends two systems:

Option 1: KRETESIL + KRETESIL FLEX

Option 2: IDROLASTIC A+B

KRETESIL is an osmotic cementitious waterproofing mortar designed for water-containing concrete structures including swimming pools, tanks and channels.

Sakhat recommendation:
Swimming Pool / Water Tank → KRETESIL + KRETESIL FLEX OR IDROLASTIC A+B

Waterproofing membranes should be protected from mechanical damage caused by construction work and subsequent system layers.

Depending on the Sakhat system, protection can be provided using:

PLYGUARD Protection Board and/or Geotextile.

PLYGUARD creates a physical protective layer over the waterproofing membrane, while geotextile can provide protection and separation within the waterproofing and insulation build-up.

Sakhat system rule:
Waterproofing membrane → PLYGUARD and/or Geotextile according to system build-up.

Reinforcement mesh improves mechanical strength and continuity in suitable waterproofing systems. ARMOFLEX 120 can reinforce systems such as MANTOFLEX and ELASTOGUM, while ARMOFLEX 160 is intended for cementitious systems such as IDROLASTIC A+B.

Yes, in the applications specified by its TDS. MANTOFLEX forms an elastic membrane resistant to UV radiation, ageing and atmospheric agents. It is suitable for applications including terraces and balconies without standing water, gutters, chimneys and protection of existing bituminous membranes.

One important difference is low-temperature flexibility.

SBS-modified membranes generally provide better cold flexibility. In the Sakhat range, TECH 500 SBS has a declared cold flexibility of -15°C, while the SINTEC APP membrane has a declared cold flexibility of -5°C under EN 1109. This makes TECH 500 SBS more suitable where greater flexibility at low temperatures is required.

In simple terms:

SBS → better flexibility in cold temperatures

APP → typically selected where greater resistance to elevated temperatures is required

For example, the supplied sheets give a flow resistance of 100°C for TECH 500 SBS and 120°C for SINTEC APP.

PVC waterstops are embedded in concrete joints and are available in different profiles depending on the type of joint and expected movement.

BENTOBAR+ is a hydrophilic bentonite and butyl-rubber swelling bar intended for construction joints. Its technical sheet specifically states that it must not be used in expansion joints.

The correct product depends on the type of joint and expected movement. RESYFLEX 151 ISO is a low-modulus polyurethane sealant for horizontal and vertical joints, while BANDEX is a waterproof thermoplastic joint system for expansion joints and critical connections.

HYDROFUGE is a colourless siloxane-based water-repellent treatment for concrete, cement plaster, brick and natural stone. It penetrates the surface without forming a visible film.

IDROSIL A provides a water-based option for porous and absorbent exterior masonry.

ALLUTEC is an aluminium solvent-based protective coating for polymer-bitumen waterproofing membranes. Its reflective properties help reduce heat build-up at the membrane surface and contribute to protecting the waterproofing system.
