We at LG Landscape Design Practice hold our reputation on a fundamental best practices guide. Not only does it save time and money for us but our clients are  presented a better finished patio or drive. Our clients can see the difference between our landscape projects and others.

Our paving projects are all worked out prior to construction on the drawing board and landscaping plan and this is key to our success. Any problems that may arise with the project are discovered at the design plan, not when the work begins.

We first carry out a detailed survey of the site to establish any underlying problems with services on-site and pipes that may be damaged in excavation and
other Health & Safety issues.

The site preparation and the excavation to the correct levels are the next step in the process. Depending on the project, the excavation depths are 10 to 15 cm for patios and 15 to 30 cm for walkways and driveways. But consideration must be always given to site conditions. For example, under-ground water tables require particular attention. Also, with the increase in rainfall levels, these elements must be taken into account and dealt accordingly. The sub-soil base should be rolled and mechanically vibrated.

The base material or foundation material is introduced at 10 cm levels and is then compacted after each level until the finished level is achieved. We use 4 cm to dust level screenings as this gives a more solid final base. In doing this, there will be no sinkages and the desired levels are better achieved.

The setting bed of either sand or concrete is then laid to a thickness of four to six  cm. In general, it is better to start in the middle of the paved area, as the desired levels can be achieved better and the correct rain water run-off slope can be gained.

At all times the use of a level should be a prerequisite and you should always have two falls on the finished project, especially in the immediate areas around the base of houses, as surface water here can cause dampness inside your home.

For block paving finishing, the application of fine sand is brushed between the joints and the surface is vibrating compacted.  This compacts the sands between the joints and the surface becomes solid.

In the case of Indian Sandstone, we recommend the use of Rompox, as this sealer will not stain your finished product.
