Drainage Systems

Direct from the draught board, our engineers knows exactly what it takes to build an effective drainage system. Due to poor planning in housing estates across the country, RAL came up with novel idea in delivering effective drainage construction services within the country. Contact us today for a quote.

Increasing urbanization has caused problems with increased flash flooding after sudden rain. As areas of vegetation are replaced by concrete, asphalt, or roofed structures, leading to impervious surfaces, the area loses its ability to absorb rainwater. This rain is instead directed into surface water drainage systems, often overloading them and causing floods, Ragus Associates Limited with its technical teams works with relevant authorities in our clients’ sites to have access to the desired and approved way to channel floods and sewage systems through the right path.

This is designed to reduce the potential impact of new and existing developments with respect to surface water drainage discharges.

Complete Renovation Services

Renovation or remodeling is the process of improving a broken, damaged, or outdated structure. Renovations are typically either commercial or residential. Additionally, renovation can refer to making something new, or bringing something back to life and can apply in social contexts. For example, a community can be renovated if it is strengthened and revived. Get the renovation you never thought possible! We will wow you with the end result, contact us today.


The renovation process can usually be broken down into several processes as you may require thus:

  • Planning
  • Engineering
  • Structural repair
  • Rebuilding
  • Finishes

Technology has had a meaningful impact on the renovation process, increasing the significance and strength of the planning stage. The availability of free online design tools has improved visualization of the changes, at a fraction of the cost of hiring a professional interior designer. The decision regarding changes is also influenced by the purpose of renovation. In case of a fix and flip objective, an ROI (return on investment) can result from changes to fix a structural issue or design flow yield or to use light and color to make rooms appear more spacious.


Most builders focus on building new homes, so renovating is typically a part-time activity for such tradespeople. The processes and services required for renovations are quite specific and, once plans are signed off, building a new home is relatively predictable. Renovations usually require all of the sub-trades that are needed for the construction of a new building. During renovation projects, flexibility is often required from renovation companies to respond to unexpected issues that arise. Projects involving renovation require not just flexibility, but a plan that had been agreed upon by multiple parties. The planning process will involve feedback from financial investors of the project, and from the designer. Part of planning will also entail the collection of data for the completion of the project and then the project plan will be revised and given consent before continuing with renovations.

Gardens & Amusement Parks

garden is a planned space, usually outdoors, set aside for the display, cultivation and enjoyment of plants and other forms of nature. The garden can incorporate both natural and man-made materials. Ragus Associates Limited has been involved in a number of recreational gardens and amusement parks constructions around the country.


Our able engineers will evaluate your needs and the environmental constraints and viability and give you the best possible structure at a great value for any kobo spent. We have been in this business for over a decade now and counting.


At the heart of our ability is the availability of the right equipment for a given project need.

Road Construction

Road construction requires the creation of an engineered continuous right-of-way or roadbed, overcoming geographic obstacles and having grades low enough to permit vehicle or foot travel, and may be required to meet standards set by law or official guidelines

Old road surfaces, fences, and buildings may need to be removed before construction can begin. Trees in the road construction area may be marked for retention. These protected trees should not have the topsoil within the area of the tree’s drip line removed and the area should be kept clear of construction material and equipment. Compensation or replacement may be required if a protected tree is damaged. Much of the vegetation may be mulched and put aside for use during reinstatement. The topsoil is usually stripped and stockpiled nearby for rehabilitation of newly constructed embankments along the road. Stumps and roots are removed and holes filled as required before the earthwork begins. Final rehabilitation after road construction is completed will include seeding, planting, watering and other activities to reinstate the area to be consistent with the untouched surrounding areas.

Processes during earthwork include excavation, removal of material to spoil, filling, compacting, construction and trimming. If rock or other unsuitable material is discovered it is removed, moisture content is managed and replaced with standard fill compacted to meet the design requirements (generally 90-95% relative compaction). Blasting is not frequently used to excavate the roadbed as the intact rock structure forms an ideal road base. When a depression must be filled to come up to the road grade the native bed is compacted after the topsoil has been removed. The fill is made by the “compacted layer method” where a layer of fill is spread then compacted to specifications, under saturated conditions. The process is repeated until the desired grade is reached.
