Slipstrip™ is therefore ideal as a bearing strip in all conditions of exposure subject to the loading conditions. The bearing strips are formed by layering two sheets together, smoth to smooth face. The tape helps prevent ingress of fines and concrete grout between sliding surfaces. The texted bottom layer is bond onto a smooth bearing substrate with Servicised® Pak Adhesive. Two layers of Slipstrip™’ can be used for sliding walls joints, pre-stressed and post-tensioned circular concrete tanks or similar structures, provided the load bearing capacity is not exceeded.
Servistrip AH 205
Active joint strip which swells when exposed to water for sealing joints in monolithic concrete
Advantages
- Effective – swells when exposed to water up to four-fold and seals joints
- Easy to apply – no special equipment or special glues required
- With inhibiting overlap layer – controlled swelling when a strip applied prevents cracking of „green“ concrete
- economical – easy to apply both to existing and new structure
- suitable for complicated concrete casts – hydrophilic strip can be bent, added to suit complicated poured shapes, and sequences can be poured
- durable – even at the repeated wet/dry cycling
Description
Servistrip® AH 205 is hydrophilic rubber strip, that is used for sealing monolithic concrete construction joints. Suitable for a variety of new concrete joints and new to existing joints. Inhibiting overlap prevents strip swelling within 7–10 days after pouring concrete. Thus expansion pressure do not cause fresh concrete spalling and concrete has time to reach its design strength. Simple shape of the strip allows to be installed in such complicated shapes as shear walls and adjoining or rough surfaces, where other methods are impossible or require special details.
Movement Joints
Servistrip® AH is only sutable for sealing construction joints. In movement joints it can be combined with PVC waterstop.

Description
Serviflex™ is a range of heavy duty elastomeric bridge expansion joints manufactured from high grade polymer rubber, reinforced with steel angles and plates with hard wearing aluminium plate.
Serviflex™ is resistant in the following conditions:
- heavy traffic and snow ploughs;
- range of movements, imposed by:
– creep and shrinkage;
– expansion and contraction caused by temperature cycles; for surfaces - transmitted braking forces;
- elastic shortage due to pre-stress;
- good skid resisting wearing surface at road level.
The size required should be selected from the chart below for the total aggregated movement expected, taking into account temperature, shrinkage, abutment deflexion, braking forces, etc. Where large scews in excess of 45° occur, Serviflex™ should be recessed a bit back from the kerb and covered with galvanised plates. On pedestrian bridges and podiums a horisontal cover plate may be also used to drainage channels. Servidem™ rubber membrane, fastened below the Serviflex™, acts to provide a secondary waterproofing layer in accordance with British Highway Agency requirements.
