Strip Seal Joint System

Strip Seal Joint System

Saradhi Engineering Strip Seal Joint System is a mechanical devices which is modified for sealing an elongated gap that is formed between two adjacent road slab sections by providing a support for vehicles to cross the gap.The Single Strip Seal Expansion Joints is a water tight and robust expansion joints for movements up to 80 mm. The main advantage of this Strip Seal Joint System is quick and cost effective installation which may drive traffic over the joint just a few hours after installation due to the use of the polymer concrete in which the steel edge profiles of the joint are bedded forming a strong, water-tight connection. Basically Strip Seal system is a unique concept for effectively sealing expansion joints in bridges and structures with large movements.By incorporating the results of recent research activities, each joint system is developed and designed to provide watertight, fatigue resistant, long-term, maintenance-free performance.

Features :

  • Ease of installation.
  • Side Retainers are extruded from structural grade aluminium
  • Movement capacity up to 125mm
  • Two styles of Elastomeric gland
  • Smooth Ride due to flush finish with trafficked surface
  • Water tight jointing system
  • COMPRESSION SEAL EXPANSION JOINTS

    SARADHI COMPRESSION SEAL EXPANSION JOINT consists of steel armoured nosing at two edges of the joint gap suitably anchored to the deck concrete and a performed chloroprene elastomer compressed and fixed into the joint gap with special adhesive girder.

    The compression seal will cater for a horizontal movement upto 40mm and vertical movement of 3mm.

    It is recommended for simply supported or continuous spans right or skew moderately curved with maximum horizontal movement not exceeding 40mm.

    SLAB SEAL EXPANSION JOINT

    SARADHI SLAB SEAL joint will consist of steel insert and elastomeric slab unit. This type of seal is recommended for simply supported or continuous spans, right or skew (less than 20 degree), moderately curved with maximum movement upto 50mm.

    SARADHI SLAB SEAL expansion joint has been used for many years with a good success rate. However, the larger size of the joint tends to create more noise under traffic.

    SARADHI Elastomeric joints are normally supplied in unit length and fixed to the deck using bolt anchors. If required tensioned cast iron bolts should be used to anchor this joint. If site drilled installations are used, the holes should be under reamed prior to fixing the bolts. An adequate length of the bolt should be de-bonded so that any relaxation over the bolt length does not result in complete loss of tension in the bolt.

    CAP SEAL EXPANSION JOINT ( OMEGA SEAL)

    It provides unique properties to withstand high water pressure in combination with large movements in all directions.

    It is an ideal solution for joints where large gap movements are expected as a result of temperature effects and/or settlement Omega profile can be manufactured in a variety of sizes to fit almost any application. It is ideal for Metro rail projects
