Application

Elastostrip, Trelleborg

Priming

All joint faces must be clean and dry and any loose material must be removed. Possible surface moisture should be removed with a blow-torch. 

Then Elastostrip Primer is brushed onto both sides of the joint. (Avoid the caulking groove present on some culverts). Primer is allowed to dry before starting the Elastostrip installation. Non-disposable brushes can be cleaned in white spirit.

Application

After the primer has dried apply Elastostrip within 8 hours, ensuring that all joint faces are clean and dry. It may be necessary to warm Elastostrip with a blow-torch to increase tack.

Apply Elastostrip of the correct size to the joint, taking care to discard the interleaving paper. On box culverts and ogee pipes heat the surface of the Elastostrip with the flame of a gas torch to obtain initial adhesion if needed. Don’t heat more than to get the surface glossy.

Positioning of Elastostrip

On box culverts position the trapezoidal section of Elastostrip to cover the sloping face of the socket. The traditional rectangular cross-sections which are smaller and should be positioned on the middle of the sloping face of the socket.

On ogee pipes position the Elastostrip on the sloping face of the spigot.

Joining Elastostrip

On manholes, box culverts and ogee pipes join the ends of the strip in a scarf joint by overlapping the ends then cutting through at 45° with a hot knife, playing a flame on the cut faces and smoothing over.

On box culverts cut the strip into the corners with a mitre joint.

Manholes & inspection chambers

On manholes with tongued and grooved joints of DN 1350 to 3000, use a double strip on the base and top joints. On all manholes and inspection chambers trim off any excess compound which extrudes internally.

On manholes the imposed loading from the upper units should be sufficient to compress the Elastostrip. Ensure that the Elastostrip is compressed by at least half its thickness before any water test.

Box culverts and ogee pipes

On box culverts and ogee pipes close the joint to an internal gap of 10 mm using a mechanical cable puller. The trapezoidal (wedge shaped)

Elastostrip will fill the joint in the middle and inside on box culverts and in the middle and outside on ogee pipes. Any squeeze-out should be cut off and smoothed flush to the wall or to the back of the caulking groove if there is a secondary sealant.
