Can I convert the Basement by self?

Though there are certainly a few aspects on which you can work, there are other areas which require professionals to cater. Your basement conversion project completely depends on the nature of the project and your skills. A professional explores each area carefully, and you can ask them if there's anything you can do by yourself.

TYPES OF BASEMENT CONVERSION

  • Dig Out Basement: you will need a dig out if your property is built directly on the foundation. The converting process includes digging underneath your property to extend the property to get further depths through a process called underpinning. After obtaining the required depth and foundation, the work will get formed.
  • New Build Basements: If your property was built from scratch, then surely you will have a built-in basement. Now the conversion process will include excavating the space before the initial construction starts. First, the shell of the Basement gets constructed before the top of the basement shell.
  • Retrofit Basement: If a space under your property is adjusted to shape your Basement, you should go for Retrofit Basement conversion type.

CAN MY BASEMENT FLOOD?

If you are facing a damp issue in your Basement, it would be not easy to find out the water resource of it. Low-lying areas always stay at risk, and without knowing the cause, it makes it vulnerable to flooding. Common cause of flooding are:

  • Burst water pipes
  •  Surface flooding
  • Groundwater
  • Poor landscaping
  • High water table
  • Drainage system issue
  • Poor quality concrete floors

WHAT IS BASEMENT WATERPROOFING

Basement waterproofing includes blocking the passage of water into the Basement, that can be achieved by external waterproofing and cementitious tanking. You can also install a cavity membrane drainage system to manage water intrusion.

Do the following, before getting started by the conversion:

  • Clean your Basement, remove all dust & debris
  • Fill the wall holes or repair dent for basement waterproofing.

Planning Permission and Building Regulations

Check with your local authority if any planning permission is required. If you have any conversion specialist with you, then they will take care of the permission procedure on your behalf.

Planning Permission for Basements

You may not need any planning permission for converting your existing Basement. As, according to the government planning portal, generally people need approval if they are building a new basement. However, it would be beneficial to check before initiating work, if you need any permission for internal or external work.

Contact your local planning office in writing to get formal approval for initiating your work.

Potential problems can occur any time, hence consider to take help from any specialist to overcome issues such as planning permission, plumbing, building regulations, waterproofing and drainage.
