Bondsure™ Membrane Series

Bondsure® PVC Tunnel Waterproofing Membrane is a kind of excellent performance of high polymer waterproof material, with polyvinyl chloride as the main raw material, added with many kinds of special additives and anti-aging components, produced by advanced equipment and production technology.

The product has excellent tensile strength, elongation, low temperature flexibility, long service life and other characteristics.

※ Material Features

1. Excellent Performance

FM Approved, high tensile strength, high elongation, can adapt to the base deformation, of excellent high and low temperature performance, can be suitable for the use in different environmental.

2. Strong Aging Resistance

Long service life, good anti-aging performance.

3. Excellent Weldability

With excellent weldability, and welding quality can be guaranteed.

4. High Plasticity

Good puncture resistance, strong root penetration resistance, can be applied to planting roof. For its good plasticity, it's convenient to do details treatment around edge and corner areas.

5. Safe & Environmental-friendly

The construction is simple, fast and environmentally friendly without pollution.

※ Scope of Application

It is applicable to expose and non-exposed roofs of steel structures and concrete structures.

It applies to waterproof engineering of basement and subway, tunnels, dams, tailing dams, etc.

※ Waterproofing Structure for Tunnel with Bondsure™ PVC Tunnel Membrane

※ Method Statement

※ 1. General

Joaboa Tech Tunnel Waterproofing System consists of a homogeneous PVC-H flexible sheet applied by disks on the polypropylene regularization layer and protected (where required) by PVC-H protection layer. The waterproofing system shall be partitioned by waterstop placed along the construction joint and welded, dividing the tunnel in watertight section able to confine water inflow coming from the possible damages occurred during the construction phases.

It has been used in some overseas government tunnel projects, like, in Thailand, Peru, etc.

The following document describes the installation procedure for the Joaboa Tech Tunnel Waterproofing System.

※ 2. Installation Process

Joaboa Tech Tunnel Waterproofing System shall be in compliance with the following steps:

Acceptance of the Substrate;

Installation of the Regularization Layer and Disks;

Installation of the PVC Waterproofing Membrane;

Installation of the Waterbar (partitioning);

Installation of the Re-injectable Hoses (backup system and crown injection point)

Installation of the Protection Layer (where required);

1) Acceptance of the Substrate

Prior to commencing membrane installation works, a final inspection of the tunnel surfaces to be lined shall be completed. An "Acceptance of Membrane Substrate Surface" checklist shall be completed to record and identify that the area of membrane installation is compliant with the following substrate requirements:

Shotcrete surfaces shall be prepared applying an additional shotcrete smoothing layer in order to remove local peaks and troughs.

Surfaces on which waterproofing systems shall be installed shall be clean, free from loose aggregate, sharp protrusions, projecting tying wire, release agents and other items which are likely to damage or affect the waterproofing system.

The shotcrete surfaces are prepared so as to achieve the smoothness and regularity required to preserve the membrane integrity. The substrate shall be in compliance with the following relationship:

2) Installation of the Regularization Layer and Disks

The geotextile regularization layer shall be applied to the shotcrete surface using steel fixings (nails + washer). The regularization layer shall be laid with sufficient slack to avoid overstress during the concrete's pouring. Geotextile layer shall be joined with the next one using a spot welding, and the overlap shall be 100 mm. We recommended to not exceed the width of 100 mm overlap in order to avoid "pocket effect" in the overlap area.

The diameter of the washer shall be checked before the installation phases in order to verify that the diameter of the nail is compatible with the internal diameter (26 mm) of the disk. The average of the fixing point number shall be 4 disks per square meter. The number and distribution of fixing point shall be evaluated by application team leader and it depends on substrate profile, overlaps, waterstops and anchoring position.

3) Installation of the Bondsure PVC Tunnel Waterproof Membrane

The waterproofing membrane shall be installed around the perimeters of the

excavation to cover the geotextile following the procedure below:

Waterproofing membrane shall be attached to the disk by a spot welding. Check always the position of the PVC sheet according to the previously one installed in order to provide the correct overlap width (automatic welding machines working range). The waterproofing membrane shall be laid with the signal layer towards the inside and with sufficient slack to prevent overstressing during concrete pouring.

Join the waterproofing sheet using the Tunnel Crawl welding machine with the parameters correctly set.

Make sure the 10cm overlap.

4) Installation of the Waterbar (partitioning)

Waterstop shall be applied along the construction joint following the procedure below:

In order to carry out the welding correctly the watorstop back and the membrane surface shall be clean and free of dust.

If dirty the welding area shall be clean.

Apply the waterstop on the PVC waterproofing membrane positioning it in the predicted section using a spot welding. The number of spot welding shall be enough to hold up the waterstop avoid to overstressing of PVC membrane;

Realize the watertight welding on each side of the waterstop for a total width of 40-50 mm;

Junction shall be realized using waterstop welding jig.

5) Installation of the Re-injectable Hoses

Re-injectable hoses (both for backup system and crown injection point) shall be installed according both the technical data sheet and manufacturer's instruction, following the procedure below:

Verify the position of the re-injectable hoses according to the technical drawings;
Check the maximum length of the re-injectable hoses according to the technical data sheet instruction;
Apply the re-injectable hoses using fixing point applied at a maximum distance of 15 cm. Fixing point shall be PVC-H tie or other type of fixing approved by the manufacturer.
Re-injectable hoses shall be completely embedded in the final lining and connected with the surface of the concrete lining using colored (white and red) termination hoses collected in the End Box. Termination hoses and re-injectable hoses shall be connected using the related plastic connector, covering the junction using the hot shrinkage sleeve.
Overlap between two subsequent re-injectable hoses shall be 20 cm at least;
Each termination hoses shall be sealed using plug to avoid the clogging of the hoses in the following construction phases;
Each termination hoses shall be marked and its position recorded in order to address the re-injectable hoses and its position even after the pour of the final lining.

6) Installation of the Protection Layer

Protection layer shall be installed as a protection additional layer.

The material shall be fully welded on the waterstop edge and spot weld to the waterproofing membrane where necessary to keep the material in position.

In presence of watertight anchors, to avoid stress on PVC waterproofing membrane, the spot weld shall be placed on waterproofing membrane welded on anchoring plate.

The number of spot welds shall be enough to allow to hold up the protection layer.

Adjacent sheets of protection layer shall be joined by a full continuous welding and the overlap shall be enough to allow correctly the welding procedure.

※ Storage and Transport

1. Different types or specifications of products should be separated, not mixed.

2. Keep it dry and ventilated, protected from the sun or rain.

3. Pile up the membranes flatwise whose stockpile height should not exceed five layers.

4. Prevent tilt or side pressure during transportation, and cover with felt if necessary.

5. Storage time is at least one year from manufacture date if the product is under normal storage condition.

※ Brand Stature
