Do you think any contractor can build a basement?

Do you think any home builder or a construction company can build a basement?

It is prerequisite for residential basement building that specialized architectural technology as well as advanced civil engineering are applied.

If you have already started a discussion with a home builder or a designer, please ask the basement building process or basement experience as follows.

Question 1 to a home builder 

Q: What process do you apply to build a basement?

A: There is no problem as basement building is assigned to a reliable partner.

Please ask if the partner is supported by the specialist of RC or ground foundation so that the knowhow to build a good basement is available.

The Question To Local Builder or Construction Company

Q: Is a specific basement construction process applied?

A: There is no problem as basement design is assigned to a reliable designer and construction is delivered in accordance with the plan.

The quality basement free from water damage can’t be built, if the same approach as the above grade construction process is applied  Please confirm what is the construction process to be applied specifically for a basement.

The Question To An Architect

Q: What is the special consideration to design a basement?

A: There is no problem once waterproofing is properly in place and a reliable subcontractor is assigned.

A basement needs special consideration for waterproofing, moistureproofing , ventilation and etc. Without them a quality basement free from condensation can’t be completed.  Please confirm what is the special consideration to be applied to design a basement.


Water leakage may temporarily stop through cutting off water, yet there is still a concern when the next leakage may occur from the vulnerable part of structure.

Some of the contractors do not have basement construction experience and knowhow, so they have too many contingencies during estimation.  Thus they may deliver overpriced estimate.

Or otherwise they may unknowingly underprice the estimate leaving many factors behind.  As a result the actual building faces budget overrun, and without additional construction cost devised the basement quality may be compromised.  Home purchase is a costly shopping, so failure is not an option.  However it is a fact that quite a few home owners, after completion of construction,  consult such a problem like this.

It is short before delivery to a client, but there is a crack on the wall allowing water to seep into, additional leakage is observed at the bottom of the wall, and the floor is flooded.

Leakage starts from tieholes  and at the bottom of the walls.
