* When removing existing concrete, Due to unable to being able to see beneath existing Concrete or Asphalt, Any concrete thicker than 100mm or deeper footings that wasn't quoted. We still discuss with you straight away because we weren't to know what was below the ground and this will be treated as a Variation
· We reserve the right to re-measure any completed works upon completion if we determine additional m2 or work has been added
· We take all practicable steps to ensure boxing is secured and kept in line with agreed areas and endeavor to advise the client of pour date, if you have any concerns, please notify your project manager within 24 hours of the pour.
· We must comply with council regulations to ensure adequate clearances and water run off is achieved.

Domestic Flooring Maintenance Guidelines
Sheet vinyl
- Domestic sheet vinyl should be maintained by weekly (or more often depending on dirt and foot traffic) washing using either hot water or a neutral pH cleaner such as Tarkoclean at the recommended dilutions. Rinsing the floor with water following the use of detergents will prevent a sticky residue remaining.
- Very strong cleaners containing Ammonia, Pine-Sol or citrus based cleaners may damage the vinyl.
- Frequency of cleaning will depend on the exposure to soiling, the more often the flooring is cleaned the
easier cleaning will be. Light or very dark colours will require more maintenance than medium tones.
- Many modern vinyls have a slip resistant surface. These may require periodic scrubbing with a nylon
bristle brush to remove dirt from the surface. Take care not to over-wet the vinyl particularly at the
edges or at seams.
- Immediately remove any excess water. NOTE: Excess water left on sheet vinyl can penetrate
seams and edges and cause vinyl to lift.
- Steam mops are not recommended.
- We would recommend the use of felt pads under furniture to help prevent scratching. Place hardboard
or similar sheeting on top of the vinyl when moving heavy objects over the floor.
- Direct contact between rubber (ie mats, furniture feet and sometimes even rubber soled shoes or
slippers) will cause permanent discolouration of the vinyl (plasticizer migration).
- Entrance mats will reduce tracking of soil or other foot borne contaminants onto the floor, therefore
extending the life of the flooring.
- Most domestic vinyls have a polyurethane surface factory applied, therefore polish is not required.
However a polish may be applied to most domestic sheet vinyls.
- Steps should be taken to ensure adequate UV protection is in place where there is direct sunlight, as
fading may occur.
Vinyl tiles/planks
- These have the same surface as sheet vinyl and therefore all of the above applies, however while not specially required you may choose to use a polish system to act as a sacrificial layer and to help prevent deterioration of the vinyl surface.
- Felt pads are especially important on these products to prevent scratching.
- Take care not to over-wet the vinyl tiles or vinyl planks particularly at the edges of planks or at
perimeters. Immediately remove any excess water.
- NOTE: Excess water left on vinyl planks & vinyl tiles can penetrate seams and edges and cause
it to lift.
Carpet
- Frequent vacuuming will remove the dirt from the pile extending the life of the carpet. Using a brush vacuum head will assist with this.
- Steps should be taken to ensure adequate UV protection is in place where there is direct sunlight as significant fading may occur.
- Vacuuming around skirting boards, under and behind furniture will help prevent insect damage.
- Stain removal will depend on the fibre type of the carpet and what has been spilled. Serious stains will
require professional help, we are able to advise on this if required.
- Always remove all solids by working from the outside toward the middle of the spill, to prevent
spreading.
- Blotting up liquids using paper towels and further diluting with plain water will deal with most spills.
- A gentle detergent (diluted wool wash) will help break down oily spills, however be sure to remove the
detergent with clean water to prevent a sticky residue.
- Blot rather than rub the pile as rubbing will damage the fibre.
- Chair mats should be used under castor chairs to prevent carpet delaminating.
When making your flooring selection please discuss maintenance requirements specific to your purchase.
BRICK TOLERANCES AND AESTHETIC APPEARANCE
It is possible for a brick veneer to be building code compliant but not have the visual look that reflects the skills of an experienced bricklayer. This is referred to as ‘workmanship quality’.
It is important to discuss with your bricklayer the aesthetic look you are hoping to achieve with your brick veneer and if possible, include them in your selection process.
The Brick and Blocklayers Federation recommends that parties to a brick veneer construction enter into a clear, written contract that sets out the expectations of parties including agreed workmanship quality standards, quality checking responsibilities and an agreement on how disputes will be managed– even if it is not a compulsory requirement under legislation.
VIEWING DISTANCE
Due to the nature of bricks no two bricks are the same and no brick is perfect when examined close- up. ASTMC90 has been adopted as the industry standard for viewing brickwork – it states that ‘for exposed wall construction chips and imperfections shall not be evident when viewed from a distance of not less than 6.1m in diffused light’.
DRYING CRACKS
During the manufacturing process hairline cracks can appear in a small number of clay bricks. This occurs during the drying process when excess moisture is removed from the clay prior to it entering the kiln. Bricks with these cracks conform to AS/NZS4455 and do not compromise the structural integrity or weather tightness of the brick.
From an aesthetic standpoint, the relevant American Standard Test Method (ASTM) has been adopted. ASTM C216-04 specifies that bricks must contain less than 5% visible cracking when viewed from a distance of 6.1 meters.
CHIPPING
Bricks may be transported several times before arriving onsite and occasionally chipping can occur. Chips are more noticeable on bricks that have a surface colour different from the body of the brick. A workmanship quality standard is achieved if imperfections, including chips, are not visible when viewed from a distance of not less than 6.1m under diffused light as per ASTM C90.
New Zealand does not have a standard to assist a Bricklayer to evaluate the level of chipping acceptable in a brick prior to laying however ASTM C216-15 has been adopted by BBFNZ.
ASTM C216-15 for a general purpose face brick (FBS textured) basically has the following requirements:
Chips from the edge should not be deeper than 8mm
Corner chips should not be deeper than 13mm.
When all the length of the chips are added up that the total is not exceed 10% of the perimeter of the brick face (as an example, the accumulative lengths of the chips for a 230mm X 75mm brick shall not exceed 61mm).
It is good practice for Bricklayers to set aside bricks that do not meet this standard and to assess whether to discard it or use it for cuts.
DIMENSIONAL CATEGORY
AS/NZS4455 Masonry units and segmental pavers’ calls for bricks to be classified into dimensional categories based on their deviation from their work size, or the size specified in manufacture.
To test if bricks meet the standard, 20 bricks should be placed in a row and the total length should be measured. This can be done with height, width and length. Tolerances for these are:
Category
Height
Length
Width
DW1
±90mm
±50mm
±50mm
DW2
±60mm
±40mm
±40mm
RUBBING
During transportation brick may rub together on the pallet. This can sometimes cause light rubbing on the face of the bricks. Excessively rubbed bricks should be discarded or used for cuts.
COLOUR VARIATION
Clay and concrete bricks are both subject to some variation in colour between batches. This is part of the inherent beauty of brick.
Unusual discolouration patterns can be limited by blending the bricks. Should there be any concern regarding significant colour variation laying should cease and the manufacturer contacted.
