Room Foundation

The CThru Room Order Layout sheet will list the dimensions of the room. The dimensions needed for the slab or deck are the room dimensions plus 1 1/2". Thus, if your room dimensions are 10' x 10', the foundation must be a minimum of 10' 1-1/2" x 12' 3".

Many potential problems can be eliminated before any construction begins by having a level, square, and plumb slab or deck. If installing the room on a new concrete slab, it may be necessary to seal the slab. This will help avoid condensation from within the room, Preferably, the room should be installed on a new slab or deck. A preexisting slab or deck needs to be in "like new" condition if used. Numerous buckles or cracks in the foundation will make it unsuitable for construction and could contribute to future leaks in an otherwise weather-tight system. Please reference your local building code for the slab, deck, or footing requirements needed to construct your CThru room.

Use the 4' level to determine the degree of the foundation's level. If the foundation is not level and the run of the slab is less than 1-1/2 inches, 2" to 3" of sold fill should be ordered at the bottom of each wall module with a glass kickplate to compensate for the slope. If the slab or deck is uneven to a large degree, a two-stage kickplate or extra solid may be necessary to construct the room. Two-stage kickplates generally have a minimum of 6" of solid below the glass kickplate. Modules with solid kick plates generally provide the most flexibility in dealing with unlevel slabs.

The room's foundation must be higher than the grade of the surrounding area to avoid drainage problems. The bottom track that will be secured to the foundation contain weep holes. Any water that penetrates the structure of the sunroom will grain out of these weep holes and away from the room. Standing or pooling water next to the weep holes could potentially block them and destroy the functionality of the internal weep system.

The general work area must be kept as organized and clean as possible. Make sure the area is free from clutter or debris before the room arrives. Potential obstructions must also be removed. These include trees, bushes, or other greenery that may make the construction of the room difficult. If needed, clean the slab or deck before construction begins. You should try to keep the construction area free from excess material, tools, or debris during all phases of construction.

Preparation on the house walls may also be needed. Examine the attachment "foot print" of the room on the house and identify any elements that may need removal, demolition, or adjustment.

The Job Site Preparation Checklist can be used as a checklist to ensure your site is ready for the room's arrival. Once completed, you can begin the installation process.

[ ] Complete Roof Type:

[ ] Yes [ ] No ------ Does the natural slope carry water away from the new foundations?

[ ] Yes [ ] No ------ Measure the drops and clearances for cap-overs and slabs (2-3" min.)

[ ] Complete ------ Can concrete be poured Sunrooms-manually or does the job require a pump?

[ ] Complete ------ If we are excavating, will the dirt be used or hauled out?

Is there enough service at the panel for the new addition?
(100 amp recommended, check at main panel)

Can the home run be concealed or will exterior conduit be needed?

Determine location of sub-panel, interior wall, exterior wall, closet and how the new home run will be routed. Will it be difficult to run?
(if an exterior run is required, document and obtain sign off from owver)
