At JDW Building Services we pride ourselves in the high standard of our work, using
at all times the correct building methods. Over the coming weeks we will be adding
new pages to our website on good building practices. We hope this will act as a good
basic guide, helping you to ask the right questions when you are seeking quotations for
your building work or helping you identify when things, perhaps aren't being carried out
to good building practices.
Preparation is everything!
Your chosen builder should start by digging out your chosen patio area down to a sound base
(preferably to the sub soil or a minimum 200mm).
Once the area is dug out, a layer of consolidated hardcore should be laid to a minimum of
100mm - 150mm. This will allow for adequate drainage under your new patio, which is
crucial to avoiding water to collect under the slabs, which during winter months can cause
damage to the slabs and the grouting between the joints. On top of the consolidated
hardcore layer, a 50mm layer of a dry lean mix 12/1 should be laid, which is the layer upon
which the slabs are positioned.
The practice of using dobs of sand and cement (known as the 5 dobs!) should be avoided.
When the slabs are laid, they should be "laid" and not hammered into position as this could
cause fractures in the slabs.
We hope this helps you ask the right questions when you are seeking quotations for your
patio or helps you identify when things perhaps aren't being carried out using good building
We are pricing up patio jobs already for this summer, for a local builder in the Hullbridge and surrounding areas to build you a new patio for you to enjoy this summer, give JDW Builders a call today!
