Self-adhesive,polymer-modified bituminous waterproofing membrane

The product is a self-adhesive SBS polymer modi­fied bituminous waterproofing sheet membrane, with a cross laminated HDPE film on one side and a silicone release film on the other.

USES

It is recommended for waterproofing or damp-proofing for concrete protection. It may be used for horizontal and vertical application for tanking be­ low ground structures, subways and retaining walls

CHARACTERISTICS/ ADVANTAGES

  • Cold applied, self-adhesive and easy to
  • Excellent adhesion to vertical and horizontal sur­
  • Excellent resistance to chlorides, sulphates,dilute al­kalis and acids.
  • Good tear and puncture resistance

FURTHER DOCUMENTS

One roll of SikaShield®-722 after deducting for the overlaps, covers an area of 18.7m x 0.98m. i.e. approx­imately 18.33 m2 per 20mxlm roll.

However,slightly reduced area coverage may occur while treating oddly shaped areas or where many joints are required

  • Pressure roller
  • Clean lint-free cloth
  • Metal straight edge for cutting
  • Hot air gun (Leister Triac)
  • Automatic thermal jointing machine (Leister Twinny or Leister Varimat,etc)

APPLICATION METHOD/ TOOLS

Surface Preparation

It is essential to create a sound and solid substrate to eliminate movement during the concrete pour. Sub­ strates must be regular and smooth with no gaps or voids. Grout around all penetrations for stability

Horizontal Blinding

The blinding must be free of loose aggregate, voids, surface irregularities and sharp protrusions. The sur­ face needs to be in a touch dry condition. SSD condi­ tion (no standing water) is also acceptable.

Vertical Surfaces

The vertical surfaces should have proper levelled bri: work, blockwork or formwork with ut any irregu­larities. For the case of sheet piles, the substrate should be made regular with a smooth finished shotcrete or sacrificial formwork to be installed

Installation

Please refer to the Sika” Method Statement: SikaProof®-7311.2 mm for detailed installation guidelines or contact Sika” Technical Services team for support

Membrane Repair

Generally, the membrane is very tough, and the exe­cution should not encounter any repair. In the most extreme cases, if for some site issues, there is any reason to do a patch work, then please contact our Sika” Technical Services team for the rectification pro­cedure

Pouring of Concrete

It is recommended that concrete is poured within a maximum of 45 days after the HOPE membrane has been installed on the sub-base (e.g. PCC). Care should be taken to avoid any damage to the membrane dur­ ing laying steel reinforcement, consolidation and com­ paction of concrete.

Care should be taken to avoid any damage to the membrane during the reinforcement laying. Addition­ ally, during placement of concrete, the vibrator needle should not touch the placed HOPE membrane. For best results use Sika” Smart Dynamic Concrete
