Block Paving Layer in Oak Tree

Block Paving Layers in Oak Tree — what to expect

When it comes to block paving installation in Oak Tree, the work typically begins with a well-prepared sub-base, followed by a screeded grit sand bed that is levelled to within a few millimetres so that tegula blocks can be laid in a herringbone bond or a more straightforward stretcher bond, depending on the driveway or patio’s proportions and the load it will carry. Local contractors across the DL2 postcode district are used to dealing with the region’s clay-rich soil and variable weather, so they are careful to include concrete-haunched edge courses to lock the perimeter and prevent any lateral movement over time. Plate compaction is then carried out in several passes, both on the bedding layer and again once the blocks are down, to settle everything evenly, after which kiln-dried jointing sand is brushed into the joints and vibrated in properly. Over the years, a lift and relay can become necessary when tree roots, heavy vehicles or simply settling have caused dips and unevenness in the paving, and this is a job that requires the same attention to detail as the initial installation, including removing the old sand, re-screeding the bed and re-compacting the entire area. Sealing is often the final touch, and while some prefer a matte finish, a good sealer will protect the blocks from oil stains, weathering and moss growth, and it is wise to apply it only after the joints have fully dried out following the jointing sand process. For those living in Oak Tree or the surrounding villages in County Durham, it is worth asking local installers how they handle drainage, what sub-base depth they would recommend for your particular vehicle weight, and whether they include the removal of spoil in their quote. If you are planning a new drive, a pathway or a full relaying of an existing area, it is a good idea to compare a few written quotations from contractors who are familiar with the local ground conditions in and around Oak Tree before you commit to a date.
