Platinum Brass Mechanical Wall Ties

Substrate Suitability:

Platinum Brass Mechanical Wall Ties are designed for use in various masonry substrates, including brick, blockwork, and concrete.

These ties are ideal for domestic dwellings and small commercial buildings up to three storeys high. They provide robust and reliable anchoring for brick or blockwork structures.

However, they are not suitable for use in perforated bricks or friable blocks with a compressive strength of less than 7N/mm², as per BRE Digest 329 Decision Tree recommendations.

Preparation:

Before beginning the installation process, gather the necessary tools: a Wall Tie Setting Tool, an SDS Rotary Power Drill, and an 11mm SDS Masonry Drill Bit. Begin by inspecting the outer and inner leaves of the wall to ensure they are sound and free from loose materials.

Confirm that the cavity width is appropriate for the selected size of the Platinum Brass Wall Ties—200mm for cavity widths of 40mm to 70mm, and 225mm for cavity widths of 60mm to 70mm. This step ensures you have the correct ties for your specific installation requirements.

Application Method:

To install Platinum Brass Mechanical Wall Ties, start by drilling a hole through the brick of the outer leaf using an 11mm SDS Masonry Drill Bit. Incline the drill slightly upwards to optimise the placement of the tie. Drill through the outer leaf until you reach the cavity. Once the tip of the drill touches the inner leaf, set the depth gauge to 70mm to ensure the correct drilling depth into the inner leaf.

Proceed to drill into the inner leaf, and if the inner leaf is made of blockwork, turn off the drill’s hammer action to prevent damage to the blockwork. Continue drilling until you achieve the required depth. After drilling, it is crucial to remove all dust and debris from the bore hole. Use an airline or air pump to thoroughly clean the hole, ensuring a clean surface for the installation of the wall tie.

Next, prepare your cordless drill by attaching the Wall Tie Setting Tool into the chuck. Set the drill’s clutch/torque to three-quarters strength. Insert the end of the wall tie into the Wall Tie Setting Tool. Begin drilling at medium speed and push the tie to the back of the drilled hole. Ensure there is “friction” when the tie passes through the outer leaf. If there is no friction, pre-expand the tie slightly before insertion to ensure a snug fit. When the clutch operates, indicating that the tie is securely set, the installation is complete.

Finishing:

After the wall tie is securely set, inspect the installation to ensure the tie is firmly in place and there is no movement. This verification step is crucial to maintaining the structural integrity and stability of the wall.

Adjust the outer leaf connection if needed to confirm that it is properly tightened. Clean up any remaining debris or dust from the installation area to maintain a neat and professional workspace.

Proper finishing ensures that the wall tie is correctly positioned and ready to provide long-lasting support.
