List 4 types of Foundations used in construction:
Strip and Wide Strip, Raft, Pad, Pile
Beam, Column, Slab, Wall
Brick, Mortar, Concrete, Steel
Door, Window, Roof, Floor
Match the type of foundation to its correct description:
Strip and Wide Strip
Involve the removal of a strip of land to a set depth and width. Concrete is then poured into the strip/trench and tamped level.
Raft
Are often used where the ground has poor load-bearing capacity.
Pad
Square or rectangular footings for individual columns or isolated load points.
Pile
Frequently used on large, heavy buildings, or where the ground has poor load-bearing capabilities.
Fill in the blank: Strip foundations involve the removal of a strip of land to a set depth and width. Concrete is then poured into the strip/trench and ______ level.
tamped
measured
painted
sanded
Fill in the blank: Raft foundations are often used where the ground has poor ______ capacity.
load-bearing
thermal
electrical
water-retention
Fill in the blank: Pad Foundations are square or rectangular footings for individual columns or isolated ______ points.
load
support
anchor
pivot
Fill in the blank: Pile Foundations are frequently used on large, heavy buildings, or where the ground has poor ______ capabilities.
load-bearing
thermal
water-retention
insulation
Which of the following statements is true about strip foundations?
They are the most expensive type of foundation.
They are arguably the cheapest form of foundation available to designers and constructors.
They do not require concrete.
They can be used on any type of soil.
Fill in the blank: Strip foundations involve the removal of a strip of land to a set ______ and ______. Concrete is then poured into the strip/trench and tamped level.
