There are many questions and concerns when installing Concrete Lintels.
Installing a Concrete Lintel is very much the same as Steel Lintels.
Let's start with some General Tips for Installation.
Inspect your Lintels to ensure they are not damaged before Installation
It should be bedded on Mortar, and the Mortar Bed should be levelled across its Length and Width.
Install a DPC - Damp Proof Course where external use.
Masonry should not overhang any flange by 25mm.
Allow Masonry to cure before applying roof loads or floor loads.
Installing Naylor Concrete Lintels
Follow the General Installation Tips, ensuring there is no damage to your Lintel before Installation.
If you have purchased a Naylor Hi-Spec Lintel, it will be marked with "TOP."
This guidance should be followed, and the "TOP" surface should always be the upper part when installed.
The Naylor Economy Range of Lintels will not disappoint on quality.
This Concrete Lintel Range is reversible, and Installation can be either way.
All Concrete Lintels should be bedded on a full level Mortar Bed
Any Weep Vents, Wall Ties and DPC should comply with current Building Regs
For Cavity Walls ensure Internal and External Leaves are built uniformly
If your Lintel supports a Concrete Floor, installing the correct Concrete Lintel is essential.
Avoid Impact Loading your Lintels at all costs when positioning a Floor Load.
When using prestressed concrete products, the concrete tendons should not be compromised by Drilling holes or anchors.
When using Naylor Lintels for Concrete Floor and Roof Loads, your Lintels Depth should be no less than the recommended 140mm.
If your Lintel Span is greater than 1200mm ensure it is adequately propped during Construction.
Prop at a Maximum 1200mm centre, and do not remove props until the Mortar is fully cured.
PreStressed Concrete Lintels
Naylor Hi-Spec should not be used in a cantilever situation.
Your Prestressed Lintel can be cut using a High-Speed Diamond Cutting Disc.
There are strict Health and Safety rules for using this equipment, and the operative should be fully trained.
Bearing at each end of Lintels should be;
100mm end bearings for openings up to and including 1000mm
150mm end bearings for opening up to and including 3000mm
200mm end bearing for openings over 3000mm
Always check with your Building Designer, Architect, and Engineer to ensure you have the correct Specification for your Project.
