• The moisture barrier mat should be stored before installation to avoid UV radiation (sunlight). Once installed and backfilled, the entire product should be concealed. This is to ensure aging resistance.
• Follow the assembly instructions carefully and ensure that the necessary drainage at the bottom is created.
• Note that lower installation temperatures can affect the system's various components and impair elasticity, strength, and adhesion. The moisture barrier is best installed during the warmer part of the year.

• Dry weather and dried/cleaned surface during installation contribute to a good result.
• During installation, consider strong sunlight and the movements of the moisture protection mat after significant temperature differences.
• Use only compatible and recommended accessories.

1. Primer K-80 (for 2.1 or 2.2)

2. Foundation Wall Membrane (3 options)

- 2.1 Adhesive Membrane BituTite (0.5m)

- 2.2 Weldable foundation membrane

- 2.3 Floating membrane

3. T-Block Remade moisture barrier mat

4. Nail and plate

5. Edge strip

6. Geotextile Geo-T N2

The drainage at the bottom is filled with at least 100 mm of gravel 8-16. We recommend using Tecca geotextile Geo-T N2 (6.) around the drainage material to prevent fine material from clogging the drainage pipe.

For self-adhesive Membrane BituTite (2.1), apply Primer K-80 from halfway up the base plate and approximately 300 mm up the wall. After drying time, apply the self-adhesive Membrane so that it covers the treated surface. Joints should be overlapped with at least a 5 cm overlap. Press-seal all surfaces carefully (e.g., with a hand roller). Use a heat gun, carefully, at lower temperatures (<+10°C) or as needed.

For Weldable Foundation Wall Membrane (2.2), install with hot air against the dry primer-treated wall (must not be sticky and uncured). See installation instructions.

For Floating Membrane (2.3) (is sensitive to frost during storage and application), apply in two layers (1 kg/sqm/application) from halfway up the base plate and approximately 300 mm up the wall. Allow to dry between applications. See installation instructions on the packaging.

Note! For higher comfort and a more moisture-proof solution in the basement, see Moisture Barrier System with insulation (item 5).

Roll out the moisture barrier with the spacers (knobs) facing the wall and with the flat edge upwards. The lower part of the mat ends approximately 50 mm above the cove. Secure the mat at the upper edge with nails, washers, and finish with an edge strip. The nail spacing is 250 mm in the mat and a maximum of 400 mm in the edge strip. The lower edge is fixed against the foundation wall during backfilling.

Use Teccas nail and washer for concrete walls or combine Teccas washer with hot-dip galvanized wire nail (length approx. 75 mm) for lightweight concrete.

On uneven (sloping) ground line, the flat part at the top is cut away and an edge strip is attached at the top to prevent soil and dirt from falling into the air gap.

When the mat is installed with insulation on the outside, the flat upper edge should not be sealed with an edge strip but according to item 5, with a water diversion (membrane or metal flashing) from the foundation wall over the mat and the insulation.

When joining, the mat is overlapped horizontally by at least 100 mm and vertically by 500 mm. Avoid joining closer to corners than 1500 mm. The top and upper edge of the mat are adjusted so that it ends approximately 100 mm below the finished ground level, with a nail spacing of 250 mm.

NOTE! When making pass-through in the moisture barrier, be careful with the seals around the hole! Use the designated sleeve (T-Sleeve) or sealing tape (Flexseal-T)!

6. Geotextile Geo-T N2

If you want to reduce heat loss through the basement exterior wall or increase the wall's temperature to achieve a drier wall and improve comfort, you can insulate with suitable ground insulation after installing the moisture barrier mat (5.).

The boards are placed against the moisture barrier and held in place as the backfilling is done gradually while the insulation is installed. Cover the outside of the insulation with Geotextile (6.). Connect with the drainage bed's geotextile at the bottom and attach it to the top of the boards.

The top is equipped with a water drainage system from the foundation wall (heavy-duty waterproof membrane or metal flashing).

The exterior basement wall does not become drier by installing a moisture barrier on its inside. However, this placement can be an option if you plan to install a moisture-sensitive material in the basement wall (e.g., plasterboard or wood paneling). Feel free to contact a moisture expert if you are unsure.

The moisture barrier is mounted on the wall and fastened with nails and washers in the cups. The top edge of the mat should be cut away so that its edges are open all around. On top of this, the moisture-sensitive panel or writing material is then mounted. It is important to leave air gaps both at the ceiling and the floor. Metal studs are the best option, but if wooden studs are used, you should place a spacer, such as blocks of hard plastic, to avoid direct contact between the wooden studs and the floor.

Air should be able to enter at the bottom of the wall, between the moisture barrier and the foundation wall, and exit through an opening at the roof. The internally exposed gypsum or wood panel should be terminated before the floor and ceiling to allow for ventilation.
