After assembly of the R.T.R.P. pipe with the rubber “chain” into the circular wall insert, the rubber is
compressed by tightening of the bolts, thus ensuring a complete watertight construction.
Link-Seals are available in various materials. The rubber elements are made of EPDM, silicone or nitrile
rubber.Bolts are of stainless steel 18-8, or zinc or cadmium plated or phosphorated steel. The pressure
rings are made of acetal polymer. As an additional advantage constructions with Link-Seals allow the
R.T.R.P. pipe a certain angular deflection and movement in an eccentric direction.A sufficiently smooth
surface of the hole inside the concrete wall can be obtained in various ways:
- By fixing a steel pipe piece with waterseal before pouring mortar.
- By drilling a hole in the wall with a crown drill with diamond inlays.
By fixing a removable plastic casing pipe piece before pouring mortar.
After removal of the casing pipe piece, the quality of the whole surface has to be checked.

Sandcoating of R.T.R.P. pipe must be carried out as follows:Sand the pipe at the spot where it fits in the wall,
over a length at least equal to the wall thickness. Apply a mixture of resin and hardener equal to that used
for bonding or laminating Wavistrong pipes with the aid of a brush, a roller or a spatula to the sanded surface.
Pour sharp sand over the prepared surface and allow the resin mixture to cure. Through this sandcoating an
excellent adherence between concrete and R.T.R.P. is obtained.
