In the video “Attaching Wood to Concrete,” Matt from Next Level Carpentry provides a practical guide on fastening wood to concrete, brick, or block foundations without using specialized fasteners like Tapcons.

This video is a valuable resource for anyone involved in remodeling projects that require secure attachments to masonry surfaces.

Matt begins by explaining the typical scenario where one might need to fasten wood to a concrete foundation, such as installing a ledger board for a bathtub.

Instead of purchasing Tapcons, Matt demonstrates a cost-effective and efficient method using standard construction screws, a masonry bit, wire, and a light-duty hammer drill.

The video showcases Matt’s step-by-step process, starting with selecting a masonry bit that is slightly smaller than the screw’s diameter. He emphasizes the importance of the bit size in relation to the screw size and the type of material being fastened.

After marking the concrete through the wood, Matt removes the wood and drills the holes to the necessary depth to ensure the screws don’t bottom out.

A key highlight is Matt’s innovative use of wire to secure the screws in oversized holes. By inserting pieces of coated stranded wire into the holes and then driving the screws alongside them, he demonstrates how to achieve a tight, sturdy fit.

This method is especially useful when the initial hole is too large for the screw.

Throughout the video, Matt provides practical tips and insights based on his extensive experience. He discusses the flexibility of this method, noting that it can be used with various materials, including old concrete, bricks, mortar, and even stucco.

This versatility makes it a valuable technique for a wide range of applications.

Matt also points out the advantages of using screws over powder-actuated fasteners, such as the ability to easily remove and reattach the wood if necessary. His clear explanations and hands-on demonstrations make the process accessible and easy to follow.
