Concrete surface preparation is a

specialised activity and demands the

use of specialised equipment. However,

since it is not always practical for a

contractor to purchase this equipment

being able to hire it from a reputable

company like Lambson’s Hire provides a

significant cost advantage.

CEMENT AND CONCRETE TECHNOLOGY

Concrete surface preparation is applied to any new or existing

concrete surfaces or structures and Lambson’s Hire recently

expanded its offering with a range of fit-for-purpose equip-

ment. The selection or use of inappropriate equipment can

have a significant impact on the contractor’s bottom line. If the required

quality finishes are not being achieved and work has to be redone as a

result, this will incur additional labour, hire and consumable costs.

“It is essential that contractors have access to best practice solu-

tions for specialised tasks such as concrete surface preparation and

this is where we play a vital role in industry. Each of the products in the

Lambson’s Hire range has a specific purpose in surface preparation,

depending on the degree of roughness required and with some overlap

of functionality apparent,” Devin van Zyl, CEO of Lambson’s Hire, says.

Equipment range

The equipment range available from Lambson’s Hire’s Concrete Surface

Preparation Division is aimed at improving the productivity and cost

effectiveness of the company’s customers. It consists of quality equip-

ment, suited to the harsh working conditions found in Africa and with a

strong international reference base.

Tough floor surfaces are tackled with ease, using the Beaver 250

floor scraping/stripping machine. “This scraper readily removes glued

down floors, commercial carpets, gummy adhesives, vinyl tiles, solid

vinyl, radial rubber tiles, sheet rubber, ceramic tiles, indoor and outdoor

sport surfaces, as well as roofing material,” says Van Zyl.

For grinding and polishing tasks Lambson’s is able to offer a

number of tools that include the versatile 65 kg Meteor 250 and 160 kg

Satellite 480 machines. These easy to use and highly manoeuvrable

machines are available with a variety of discs for various tasks. The

Meteor 250 is a single disc electric floor grinding machine, and the

Satellite 480 is a triple disc planetary machine which is available in both

electric and petrol options.

On the other end of the scale, 125 mm handheld diamond grinder

is perfect for use in confined areas due to its compact size and mass of

only 2,6 kg. This grinder is typically used for the grinding and polishing

of concrete on beams, columns and stairways. The grinders are

complemented by the Edco walk behind floor scarifier. This machine

has a working width of 250 mm and is used for surface marking removal,

levelling, texturing and grooving.

Using compressed air to hammer piston-mounted bits into the

concrete surface, scabblers typically roughen the concrete surface

more than grinding or scarifying. Lambson’s Hire stocks a three headed

hand-held scabbler that weighs 4,7 kg, with a blow per minute rate of

2 800 x 3 and an 11 headed walk-behind scabbler, weighing 72 kg

capable of covering 30 m

/h at a depth of 6 mm, with a rate of 2 200 x

11 blows per minute.

The smaller scabbler is ideal for the removal of plaster or the crea-

tion of a rough profile on walls or columns while the larger machine is

used for preparing concrete surfaces for new concrete/grout/mortar/

thick cementitious layers; for reducing concrete levels and for rectifying

over poured concrete slabs.

During the preparation and cleaning of floor surfaces, the presence

of dust can be an environmental and health hazard. Lambson’s tackles

this with two purpose-built dust collectors, capable of catching and

collecting even the finest of concrete dust. “These machines feature

a special filter shaker which allows all dust to be removed from the

filter after operation. For varying needs, we have a smaller 25 litre unit

weighing 31 kg and a larger 100 litre, 65 kg dust collector. Both are

supplied with anti-static hosing for shock prevention.

In addition to its range of concrete preparation products,

Lambson’s Hire also provides a 20HP

self-propelled concrete/road saw that

has a maximum cutting depth of 190

mm and is used for cutting all types

of concrete and bitumen.

“To maximise the perfor-

mance of this specialised

equipment on hire, Lambson’s

Hire’s Concrete Surface Prepa-

ration Division offers customers

assistance with on-site commis-

sioning,” Van Zyl concludes.
